Abstract
The utility model relates to an outdoor nonmetal bird pecking prevention aerial optical cable which can lead an outdoor nonmetal layer stranding type optical cable for communication not to be pecked by birds when being aerial. The outdoor nonmetal bird pecking prevention aerial optical cable comprises an optical fiber, a loose tube, fiber grease, a central reinforcement and a sheath, wherein the loose tube comprising the optical fiber surrounds the central reinforcement, is internally provided with the fiber grease and is packed by a belting; the sheath is sheathed outside the loose tube; the belting is internally provided with a water-proof material; and the sheath is a red polyethylene sheath. The central reinforcement is externally provided with a central reinforcement cushion. According to the utility model, the outdoor layer stranding aerial optical cable for the communication can be prevented from being pecked by the birds when being laid aerially.
Description
Technical field
The utility model relates to the optical cable technology field, and it is a kind of outdoor aerial optical cable of nonmetal anti-unfirmly closing of anti-unfirmly closing in definite saying.
Background technology
Nonmetal layer-twisted type communication is that optical fiber is inserted in the loose sleeve pipe of being made by the plastics of high-modulus with outdoor aerial optical cable, fills the compound that blocks water in the sleeve pipe.The center of cable core is a nonmetal strengthening core (FRP), and loose sleeve pipe (and gasket for packing) is twisted into compact and circular cable core around the center strengthening core, and the slit in the cable core is filled with the filling material that blocks water, and covers black polyethylene sheath stranding outward.This optical cable does not have metal construction, and anti-electromagnetic performance is good, and total cross-section blocks water, and humidity resistance is good, and external diameter is little, in light weight, low-loss, low chromatic dispersion, is applicable to built on stilts, the pipeline of numeral or analog transmission communication system.
Outdoor aerial optical cable is built on stilts to lay often regular meeting by unfirmly closing; for prevention layer-twisted type communication is maked somebody a mere figurehead when laying by unfirmly closing with outdoor aerial optical cable; now invent the outdoor aerial optical cable of a kind of nonmetal anti-unfirmly closing, by unfirmly closing in the time of can effectively preventing layer-twisted type communication to lay with outdoor aerial optical cable is built on stilts may.
Summary of the invention
The purpose of this utility model provides a kind of outdoor aerial optical cable of nonmetal anti-unfirmly closing of anti-unfirmly closing, make nonmetal layer-twisted type communication with outdoor optical cable when built on stilts not by unfirmly closing.Through discovering repeatedly, all birds are all compared sensitivity to red color and fear, cable is by unfirmly closing when preventing outdoor built on stilts wiring, and changing black polyethylene sheath commonly used at this is red pe sheath, just our outdoor aerial optical cable of said nonmetal anti-unfirmly closing now.
The utility model has the advantages that:
1. when making nonmetal layer-twisted type communication with the built on stilts wiring of outdoor optical cable not by unfirmly closing.
2. this optical cable does not have metal construction, and anti-electromagnetic performance is good.
3. fill extraordinary fine cream in the loose sleeve pipe, 100% cable core is filled total cross-section and is blocked water, and humidity resistance is good.
4. external diameter is little, in light weight.
5. low-loss, low chromatic dispersion, be applicable to built on stilts, the pipeline of numeral or analog transmission communication system.
6. accurately control optical fiber excess length and guaranteed that optical cable has good tensile property and temperature characterisitic.
7. shell material itself has good anti-hydrolytic performance and higher intensity, fills in the pipe with extraordinary ointment, and optical fiber has been carried out key protection.
8. the PE sheath has good anti-ultraviolet radiation performance and environmental stress cracking resistance.
9. good material water-proof material prevents the technology controlling and process and the apolegamy of quality matetrial that it is unique that optical cable vertically seeps water, and makes optical cable have the mechanical property and the environmental performance of brilliance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a process chart of the present utility model.
1 is presumable gasket for packing among the figure; The 2nd, central reinforce member; The 3rd, presumable central reinforce member bed course; The 4th, material water-proof material in the cable; The 5th, band and presumable bundle yarn, inner cushion layer; The 6th, optical fiber; The 7th, fine cream; The 8th, contain loose sleeve pipe or other light unit of optical fiber; The 9th, red pe sheath.
Embodiment
The outdoor aerial optical cable of nonmetal anti-unfirmly closing comprises optical fiber, loose sleeve pipe, fine cream, central reinforce member, sheath, the loose sleeve pipe 8 that contains optical fiber 6 is centered around around the central reinforce member 2, in the pine sleeve pipe 8 fine cream 7 is arranged, pine sleeve pipe 8 is wrapped up by band 5, overcoat sheath 9, material water-proof material 4 is arranged in the band 5, and sheath 9 is red pe sheaths.Central reinforce member bed course bed course 3 is arranged outside the central reinforce member 2.Also gasket for packing 1 can be arranged in the band.In the band 5 yarn of bundle, inner cushion layer can be arranged.
This product selects for use the layer-twisted type structure to produce:
1, optical fiber pine cover lining
For not being subjected to external action, protection optical fiber outside optical fiber coating, do not squeeze into the process of one deck suitable plastic pine cover and filled composite cushion.
2, stranding
Stranded with loose sleeve pipe, presumable gasket for packing, reinforcement (FRP) nature to together, excessive for preventing yarn-binding tension, be adjusted to inertial states, purpose be element is closed as a whole.
3, oversheath
The restrictive coating of optical cable is used for protecting cable core, makes cable core avoid the influence of extraneous mechanical effect and environmental baseline, and here we select red pe sheath for use.
The outdoor aerial optical cable of the nonmetal anti-unfirmly closing of the utility model at first with optical fiber pine cover protection, is twisted into cable core with non-metal reinforcement member again, protects finished product behind the red pe sheath outward.
